PHYSICAL CONSTRAINTS ON MANTLE MODELS

PHYSICAL CONSTRAINTS ON MANTLE MODELS Mantle reservoirs 

It has also been suggested that the relatively high lower mantle viscosity may further promote the preservation of geochemically distinct domains. Mantle viscosity has been extensively studied using a variety of techniques. Viscosity models have been obtained from plate reconstructions and geoid inversions (Ricard and Wuming 1991 Ivins et al.
